When someone creates a living trust in California, they name a successor trustee to take over when they pass away or become incapacitated, as the trust’s terms provide. Most people assume this role is simple. The trust avoids probate, assets pass privately, and the family moves forward. That is partly right, but trust administration is a formal legal process, and the successor trustee carries real legal responsibilities. Mistakes along the way can expose the trustee to personal liability.
If you have been named a successor trustee in Fremont or anywhere in Silicon Valley, or you are a beneficiary trying to understand what happens next, this guide explains the process.
What Is Trust Administration in California?
Trust administration is the legal process of settling a trust after the person who created it dies: gathering assets, notifying beneficiaries, paying debts and taxes, and distributing what remains according to the trust’s terms.
The person who created the trust is called the settlor or grantor. When they pass away, the trust does not simply pay out on its own. The successor trustee must step in and administer the trust in accordance with California law, primarily the California Probate Code, and the terms of the trust document.
This is one of the central benefits of a revocable living trust. Assets properly titled in the trust generally pass without probate, which can save beneficiaries significant time and money. Assets that were never transferred into the trust may still require separate procedures. And avoiding probate does not mean there is nothing to do.
How Is Trust Administration Different From Probate?
Unlike probate, trust administration in California usually happens privately, outside of court, but it still follows strict legal rules.
Probate is the court-supervised process for distributing assets that were not placed in a trust or otherwise structured to avoid it. It is public, often slow, and can be expensive. Trust administration generally happens outside of court and is usually faster and more private.
That said, trust administration is not informal. The California Probate Code sets out the duties a trustee owes to beneficiaries, including acting in their best interests, keeping accurate records, avoiding conflicts of interest, and making distributions only as the trust directs. If the trust is improperly administered, beneficiaries can petition the court to hold the trustee accountable.
What Does a Successor Trustee Actually Do?
A successor trustee must review the trust, notify beneficiaries and heirs, gather and protect trust assets, pay valid debts and taxes, and distribute what remains as the trust directs.
Here is a closer look at what that process involves:
1. Review the Trust and Obtain Death Certificates
The trustee needs certified copies of the death certificate and a thorough understanding of what the trust says before taking any action. The trust document controls how assets are managed and who receives them.
2. Send the Required Notices
When a revocable trust becomes irrevocable because of the settlor’s death, California Probate Code Section 16061.7 generally requires the trustee to serve a notice on beneficiaries and heirs within 60 days. The notice explains the recipient’s right to request a copy of the trust terms and the deadline to contest the trust. Under Section 16061.8, a contest is generally barred after the later of 120 days from service of the notice or 60 days after the trust terms are delivered during that 120-day period.
3. Gather and Inventory Trust Assets
The trustee must identify and take control of every asset the trust holds, including real property, bank accounts, investment accounts, business interests, and personal property. The trustee should also identify any assets left outside the trust, which may need separate transfer procedures.
4. Manage Assets and Address Debts
During administration, the trustee must protect and manage trust assets responsibly. Before distributing anything, the trustee must identify known debts, decide whether to use California’s optional notice-to-creditors procedure, pay valid claims, and keep appropriate reserves rather than distributing too early.
5. Handle Tax Filings
The trustee is responsible for making sure the decedent’s final income tax returns are filed, along with any required trust income tax returns and, for larger estates, a federal estate tax return. California does not have a state estate tax. For 2026, the federal estate tax exemption is $15 million per individual, up from $13.99 million in 2025.
6. Distribute Assets to Beneficiaries
Once debts and taxes are resolved, the trustee distributes assets as the trust directs. For real property, this means preparing and recording new deeds. For financial accounts, it means retitling or transferring funds.
How Long Does Trust Administration Take in California?
Most California trust administrations take between six months and a year, though complex assets, creditor issues, or disputes can extend the timeline.
There is no fixed deadline for completing trust administration. The contest period, creditor claims, tax filings, and asset sales all affect timing.
In Fremont and across Silicon Valley, trust estates often include real estate, stock options, and business interests. These assets require careful valuation and, in some cases, professional appraisals, which add time and complexity that simple bank account distributions do not.
What Are a Successor Trustee’s Fiduciary Duties?
A successor trustee is a fiduciary and must act with loyalty, impartiality, and reasonable care in the best interests of the beneficiaries.
California Probate Code Section 16002 requires the trustee to administer the trust solely in the interest of the beneficiaries. Section 16003 requires the trustee to deal impartially with all beneficiaries, which does not always mean equal distributions. Section 16040 requires the trustee to administer the trust with reasonable care, skill, and caution.
Self-dealing, such as buying trust assets at below-market prices, or favoring one beneficiary over another can lead to legal action against the trustee.
Common Mistakes Successor Trustees Make
Many trustees make costly errors because they do not realize the role carries legal weight from the moment they accept it.
Some of the most common mistakes include:
- Distributing assets before debts and taxes are fully resolved
- Failing to send the Section 16061.7 notice on time
- Mixing trust assets with personal funds
- Not keeping detailed records of every decision and transaction
- Acting on what family members say rather than what the trust document says
Trustees who make these errors can face personal liability. Beneficiaries can petition the court to surcharge the trustee, meaning the trustee may be ordered to repay losses from their own funds.
Does Trust Administration Require Court Involvement?
Most California trust administrations are handled privately, but disputes, creditor issues, or unclear trust terms may require a court petition.
A successor trustee generally does not need court approval at each step. Court involvement may become necessary if beneficiaries dispute the trust’s terms, if a creditor dispute arises, or if the trustee needs guidance on an ambiguous provision. Trust petitions are generally filed in the superior court of the county where the trust’s principal place of administration is located, which may or may not be the county where the decedent lived.
What Happens If There Is No Successor Trustee?
If the named successor trustee cannot or will not serve and the trust does not name an alternate, California Probate Code Section 15660 provides a process for filling the vacancy, which may include appointment by the court. In some cases, a professional fiduciary may be appointed to administer the trust.
This is why it is worth reviewing your own trust periodically to confirm your named successor trustee is still willing and able to serve.
